Severity High
Affected Packages 12
CVEs 1
Info Packages Vulnerabilities

The system could be made to crash or run programs as an administrator.

Alexander Popov discovered that the N_HDLC line discipline implementation
in the Linux kernel contained a double-free vulnerability. A local attacker
could use this to cause a denial of service (system crash) or possibly gain
administrative privileges.
